PENDULUM

A pendulum is a weight suspendedfrom a pivot so that it can swingfreely.

When a pendulum is displacedsideways from its resting equilibriumposition, it is subject to a restoringforce due to gravitythat will accelerateit back toward the equilibrium position.

When released, the restoring force

combined with the pendulum's mass

causes it to oscillate about the equilibrium

position, swinging back and forth.

The time for one complete cycle, a left

swing and a right swing, is calledthe period.
